 Measure the wave amplitude with a caliper; in different filtering modes, ×0.25 is 2.5 ± 5% (mm), ×0.5 is 5.0 ±% 5 (mm), ×1 is
10.0 ±% 5 (mm), and ×2 is 20.0 ±% 5 (mm). Comparing the amplitude of the square wave with the ruler, the error range
should be within 5%.
 When calibration is complete, select “Stop Calibration” to exit.
